When Google spiders and enumerates pages in a forum, some of the addresses it finds are just forum and page number -- you know, those pages that just list thread titles in the forum with links to click on, like one that you referenced (converted to parallaxinc.com):

I had some urls that did not convert. Then I realized the number at the end was duplicated in some way. I removed the duplication and it converted. This converter really works great! But you didn't reply to the key point. Can you make it a sticky?
